Nuturing the Older Brain and Mind, by Pamela M. Greenwood and Raja Parasuaman provides a comprehensive review of the current research in cognitive aging. In the latest Brain Science Podcast (BSP 87), Dr. Greenwood explains that brain aging and cognitive aging are not the same thing; the typical brain changes that are associated with normal brain aging (such as shrinkage) are not reliable predictors of cognitive decline. Fortunately, even though normal brain aging is still not well understood, the discovery of brain plasticity is shifting the focus of research. Not only does brain plasticity offer new hope for people who suffer strokes and other brain injuries, it also suggests that life style choices influence cognitive function at all ages.

Nurturing the Older Brain and Mind is intended for an academic audience but it is accessible to everyone. This month's interview with Dr. Greenwood (BSP 87) focuses on dispelling the most stubborn myths about brain aging. We also talk about the practical steps we can all take to help maintain our cognitive performance.
